European Journal <strong>of</strong> Social Sciences – Volume 5, Number 3 (2007) But more than one celebrity has no effect on consumer perception when they appear in high involvement product or service ads. The results showed that there is no significant difference in consumer perception for single celebrity and multiple celebrity ads for high involvement product or service. As for high involvement product or service ad the argument in that ad is more important for consumer compare to the celebrities in that ad. Consumer attitude is influenced by the argument not due to number <strong>of</strong> celebrities in that ad (Kahle & Homer, 1985). The results from this research supported the Elaboration Likelihood theory (Petty and Cacioppo, 1981) and Social Adaptation theory (Kahle, 1984; Kahle & Timmer 1983) according to which for low involvement product or service ad celebrity is a good option but for high involvement product or service ad the argument is more important to influence consumer attitude. This research could be a good extension <strong>of</strong> knowledge on celebrity endorsement as consumer perception remain same when we have one celebrity or when we have multiple celebrities in high involvement product ads so for advertiser and marketers <strong>of</strong> high involvement product or service argument should be <strong>of</strong> prime concern compare to number <strong>of</strong> celebrities in an ad. While for low involvement product and services multiple celebrities’ endorsement can play its magic but two points should be considered before going for more than one celebrity in an ad. First matching the celebrity with the compatible meaning which the brand is or product is using as multiple celebrities can lead to confusion about the brand identity (Erdogan & Baker, n.d., p.13). Second the target market should be divers enough because for diverse target market more than one celebrity are required to cater all <strong>of</strong> them (Hus & McDonald, 2002) Limitation and Recommendation The primary limitations are related to the generalization <strong>of</strong> the research results. The first issue is related to the sample, as student sample has limited external validity which limits the generalization <strong>of</strong> the results (Lynch, 1982). Second generalization issue is related to the stimulus, ads which were used as a stimulus were all female celebrities ads, male celebrities ads and males and female celebrities ads may produce more constructive results. The future research can use electronic media ads as stimulus. Because electronic media ads can effect consumer perception differently compares to print media advertisements. 130
